of sending the heated exhaust gases either through the body, to provide body heat, or through the vertical, along-
pabrexhaust-stack, same as a conventional truck. Thus, when the conditions and situation requires a heated body, the
body can be heated. When a heated body is not needed, flip the diverter valve and the exhaust gases are routed out the
stack pipe. In addition, it should be noted that while the exhaust gases out of the diesel engine are 900°F to 1100°F, the
5 inch diameter exhaust tubing in the airstream under the truck is cooled somewhat by the time it reaches the body. Upon
entering the body, the approximately 7000 pounds of steel and the even heat distribution paths under the 1/4 inch thick
steel plate floor guarantee that the engine exhaust gases will not cause an over-heating problem. The body has too great
a mass and heat surface area in the truck's moving airstream for over-heating to be a problem. Further, the exhaust
gases enter the body on the curb side and the driver's access ladder is on the opposite, road side.
d. The use of a heavy tarpaulin is needed for hot asphalt mix, however, legislation has been passed in a number of
states requiring a tarpaulin be in place and secured over all trucks loaded with loose payloads. Users report that climbing
up on the box and dragging a tarpaulin over the load is far too expensive in worn and torn tarpaulins and in accident costs
from driver falls. Commercial users buy a properly engineered tarpaulin cover and emplacement assembly, cranked into
both cover and retract position by the driver, all while standing firmly on the ground along side of his truck. Again, the
initial cost is higher, but the overall costs and problems are lower, resulting in a substantial net savings.
e. The Suggestor's interest in reduction of hazards and in realizing a savings of the CCE dump truck is very much
appreciated. In this instance, with the selective type body heating system, the advantages of being able to heat the body
when and as needed are considered to be well worth the 1% cost increase on each truck.
